From the Executive Overview, "Constitutionally unique, the National Guard remains capable and ready to rapidly respond to complex civilian and military challenges going forward. From the local to national scene, the National Guard remains a proven performer at home and abroad. Today's threats demand the full capability the National Guard currently provides, and its potential to adapt to meet critical future missions such as cyber threats and complex infrastructure system protection. The National Guard rapidly and competently expands the operational capacity of the Army and the Air Force by providing trained, equipped and ready Soldiers, Airmen and units. These units range from small, elite teams to highly effective brigade, division and air wing organizations across the spectrum of combat, combat support, and combat service support functions. Over the past decade, Guard members have deployed more than 750,000 times in support of operations in Iraq, Afghanistan, the Balkans, the Sinai, the Horn of Africa, and other locations across the globe. Our nation has invested tens of billions of dollars in the National Guard and it has yielded a return that has produced one of the best trained, best equipped dual-mission forces in our 376-year history. The National Guard also blends military and civilian skills, including substantial untapped cyber expertise well-suited to understanding and working in an increasingly complex global environment."
